p Myinvention relates to fan apparatus for use v'in wells .for elevatingoil, water, or the like, froml the bottom of a'wel-l'to the surface y lvshowing a still further. modified form,'in

of the ground',` :andfaim's toprovidefa novel and improved device ofthischaracterfwhich may be conveniently'- larrangedy ina well *for uefficiently elevatingoil or water therefrom.

' The invention contemplates the'y provision of an inlety pipe leadingdown into theY well from the surface of thegr'ound'and opening intoasuction or vacuum chamber having an inlet valve leading therein'forpermitting the rentrance of-oil-or waterlfroin the well into thechamber, vsaid inlet'pipe'opening intoI the suc#v to-n or vacuum chamberin alignment witha passageway in communication with an outlet pipeleading to the' surface of thef'ground so thatv upon the forcing ofwater or other liquid down the inlet pipe intothepassageway a suctionfwill created in thesuction or vac-` uum chamber which causes the wateror oil in the well ftoen'ter the suction or vacuum chamber throughthefvalve and be 'carried to the surface of the groundv with the firstnien;

'It is alsdan object of theinventi'onto-'providex an apparatus oftheabove indicated character, which is simple and substantial inconstruction, Vwhich can lbe manufactured economically, and whichywillloe thoroughly eflicient and practical in use. j y, With theforegoing andotherobjects in view, ywhich will/befapparent'as thedescrip'- tion proceeds, the invention residesfin the construction andarrangement of parts, as hereinafter described and claimed, it belngVunderstoodthat changes canbe made within the scope ofwhatis claimed,without` depart- 40 ing from the spirit of the invention. j

The invention is illustrated inV the raccompanying drawings, wherein: yv 1 Figure 1 isj'a longitudinalsection through my improved apparatus,showing. the upper 5 ends ofthe inlet `and outlet pipes broken away, :uVr Figure 2 is a cro'sssection taken on line 24-2 of Figure 1, f f Y YFigure 3 is a fragmentary sectional View of a modification of the meansof 'communication o f `the inlet pipewith; the outlet pipe in thesuction or vacuum chamber, and F lgure 41 is' another fragmentarysection which the 'distance between the inlet passageway andthe outletpassageway may'befadf justed for causing greater or less. suction 0I'vacuum in the'suction chamber.

`leferringto the drawings,the numeral 10 designates a relatively largercasing extending intoa well fromthesurface ofthe ground to e, pointbelow the vlevel-ofliquidinthe V`Wel A i v On the lower end of vthe'casinglO is threaded, as at 11, armain body 12.`v`v The inainbody `12V-has -arrangedktherein and 'spaced from the Walls thereof a vacuum forsuction chamber. 13, Yopening out at lone Side Aof the body 12, as at14,'saidcha1nber .beingA cylindrical in'shapeand provided atitsinner endwith a cylindrical depending Vportion or outlet'15.- Rising from theupper wallofthe suctionchamber above the depending portion o1' outlet 15isa collar 16 into which is threaded'the lower end of an inlettube 17extendking'gtothe surface of the ground/andV is Varrangedin the casing10 adjacent `onehside u thereof. v

lDepending fromvfthe upper wall of the vacuum or suction chambercentrally of the` depending .portion 15 and on a line withthe center-ofthe collar 16 is a restricted depending sleeve 18, on the lower endofwhich is threaded a nozzler19, the lopening through whicli istapered-and restricted, asV at 20.

lThreaded into theupper end' of the Ldepending'sleev'elS atthe center ofcollar 16 is a tubular member 21 which extends upwardly intothetubel7`and has its upper end closed,

as at 22. This tubular member is of a great deal less size than the tube17 so that a space is formed aroundthe same for'c'atching and holdingscale, thus forminga scale trap, las indicated by the. numeral 23, andinthe upper Apartfof its cylindrical Wall is a series of openings 24 forpermitting the entrance of liquid from'the tube 17 into the tubularmember4 21.` As the'openings 24 are arranged above the lower portion' ofthe tubular member 21, it'can thus be seen that scale collected aroundthe tubular member will not enter said openings.

The depending portion or outlet of the vacuum or suction chamber isthreaded to receive the upper end of a tubular member 26 the openingthrough which forms a jet race, enlarged at the upper end, as at 27 togradually merge into the outlet of the suc tion or vacuum chamber. Themember 26 is in alignment with thev nozzle 19 on the depending sleeve 18soV i that `liquid forced through said nozzle will be directed'into thepassageway or jet race. Gn the lowerV end of the main bod-y 12 isthreaded or otherwise secured an enlarged cup-shaped bowlY 28 into whichthe member 26 slightly protrudes, said cup-shaped bowl being incommunication with the mainbpening through the bodyv 12 and the maincasing` 10. rlhe vacuum or suc- '.ion chamber 13 is internally screwthreaded,

as at 29, adjacent the point Vwhere it opens exteriorly oil the body 12to receive a. flanged collar 30 having an inclined valve seat 31 at itsinner 1 end with, an inwardly projecting ,iug`32f at the upper endofsaid seat and to which is pivoted an .arm` carrying a flap valvef34,adapted -toengage `the seat 31 .for

' normally` closing the vaci'ium or suction CII chamber 13. By incliningthe valve-'seat and pivotally connecting the lapper valveV at a pointslightly inwardly thereof the weight:

of the iapper valvewill cause the sameto normally bein closed' position.A

F or `stabilizing vthe tube 17 within the casing 10leaf springs ,36 bearagainst the same at suitable intervals throughout the length of saidtube, said springs being riveted to the casing as at 35 with their freeends 37 bearing against the tube, and though I have shown Vbut onestabilizing spring, it is to be under# stood that they are to beprovidedthroughout the entire length of the casing and tube. Y

.In operation of my improved apparatus, a liquid such as water or oil isforced under pressure 'down the tube 17 from the surface of the groundto the lower end of said tube, and when the liquid reaches thexbottom ofthe tube 17, it will pass through the openings 24 in the sleeve ortubularinember 21 and thus be forced through the restricted dependingsleeve 18 ata relatively high rate of speed, due to the fact that theopening in the sleeve is a great deal smaller than the open ing throughthe tube 17. The liquid ,entering the sleeve 18 passes through thenozzle 19 and the speed or velocity thereof is increased to a higherrate and is forced into the jet race or opening through the'member v26.As the liquid passes from the nozzle into the jet race, a vacuum orsuction is created in the vacuum or suction chamber' 13, thus causingthe flap valve v34 to open and oil or water, whichever iscontained'inthe well, drawn into the suction or vacuum chamber, vfromwhich it Will be carried'with the liquid forced Y forced Y the well.

down through the tube 17 into the cup-shaped bowl 28, communicating withthe casing 10.

hus the liquid forced through` the tube 17 and liquid entering throughthe valve 34 will rise in the casing 10 to the surface of the groundwhere the same is drawn away. It is to be noted that by arranging thetubular member or sleeve 21 inthe tube 17 that all scale or foreignmatter contained in the liquid down through the tube 17 will collectaround the Vexterior of'said member 21 and not enter the interiorthereof which would 'probably cause clogging ofthe nozzle 19.v It

is to be noted that the nozzle 19 is arranged Vat a point in the vacuumyor suction chamber where all Aliquid Yforced therethrough will beforced directly into the opening or jet'race in themeinber 26, thuspreventing such liquid entering thevacuum or suction chamber 13.

Inligure 3 of the drawings, I have shown a modified form of nozzle,wherein I have provided Yan, outwardly flared opening 40 at thedischarge end of the nozzle which receives therein a tapered on pointedend 41 of a ypin 42 arranged in themember 26, said pin 42'being'carriedby the lowerend of the member 26 by means of webs, orrthelike, 43. By flaring` the discharge opening of the nozzle 19V andarranging a tapered pin in said opening, the liquid forced through Ythenozzle will be retained at ahigh rateof speed durin its-short passage inthevacuum or suction chamber, thus causinga greater vacuum or suction inthe chamber .for drawing oil or Water into the same from the bottom of f`Inldigure 4 ofthe drawings, I have shown the sleeve 18 as beingexteriorly screw threaded through the upper wall of the vacuum orsuction chamber so that'the distance or space between the nozzle and thejet race may be, adjusted for increasing or decreasing suction in thechamber 13. In this form of my invention, the tubular member 21 is anintegral part of the sleeve 18 so that both of said members are movedupon adjustment of the sleeve. .While I have shown the s leeve'as beingthreaded foradjustment of the nozzle, it is to be understood thatvarious size nozzles may be usedfor permitting such adjustment and thata nozzle of greater or less length may be threaded into the sleeve 18shown in Figure 1 ofthe drawings for permitting said adjustment,
